How can I seperate chron emails from system emails? everything goes to spam

[captainolive]

My system emails all go to spam, but in the system settings, I have two emails setup: 

one is admin@site.com and is listed as the general system email, as well as the STMP User in the STMP configuration settings. 

and the other is donotreply@site.com, this is listed as the System Emails From Email at the bottom of the mail settings tab. 

 

Despite this, all chron reports, domain sync reports, tickets, invoices, welcome / setup emails all come from admin@site.com thus I feel this has attributed to it being spam.

I don't understand what other settings I should configure to separate important emails for customers from all the internal emails that are also sent out from the same address. 

 

Any advice? I don't know how to quantify this question in a google search and many articles I find seem to explain something unrelated to what I need.  

**edit**

To add, I have both emails setup in cpanel as well. 

Is it possible that switching to a gmail account, and configuring the provider as gmail just fix the issue entirely if my personal email stmp host is compromised in spam filters?

I've spent the last 3 days rebranding which resulted in using a new domain. 

Properly setting up chrons and emails once and for all on a new domain got the new emails out of spam so hopfully it remains smooth sailing from here.
